Lickety Splits sells ice cream cones for $1.75 each. The Yummy Tummy sells ice cream cones for $2.15 each but will give you a free cone after you buy 5.
One store is offering a better deal. How much will you save if you buy 6 ice cream cones at that store?
6 * 1.75 = ?
5 * 2.15 = ?
Compare the two totals.
1.75 * 6 = 10.50
2.15 * 5 = 10.75
25 cents difference
To determine which store has a better deal, you need to compare the total cost of buying 6 ice cream cones in each store. Let's first find the total cost of buying 6 cones at each store:
At Lickety Splits:
Cost per cone = $1.75
Total cost = 6 cones × $1.75/cone = $10.50
At Yummy Tummy:
Cost per cone = $2.15
Total cost = 6 cones × $2.15/cone = $12.90
Now, let's calculate the savings at Yummy Tummy. Since they offer a free cone after buying 5 cones, you will only pay for 5 cones:
Cost per cone = $2.15
Total cost = 5 cones × $2.15/cone = $10.75
To calculate the savings, subtract the total cost at Yummy Tummy ($10.75) from the total cost at Lickety Splits ($10.50):
Savings = $10.50 - $10.75 = -$0.25
If you buy 6 ice cream cones, you will actually save $0.25 by purchasing from Lickety Splits instead of Yummy Tummy.
